Solve by using the Gaussian elimination method. For instance:

Question

5x+2y=3
3x+4y=13

Answer 1

Given equations are 5x + 2y = 3 ---> (1)

3x + 4y   = 13 ---> (2)

Convert the equations in to matrix form.

AX  = D

A  is coefficient matrix , X  is variable matrix and D  is constant matrix.

From Guass-jordan method

The augmented matrix is [AD ]

are represents first row and second row.
